the guy i bought it from told me it needed to be ripped apart i found an 02 sensor wire disconnected.... this could def be the problem right?

 

Probably fuel pulsation dampener or the metal check valve for the fuel return. Very risky as it can easily start a fire. Check the 3rd gen FAQ thread for past threads on the topic:

O2 sensor has nothing to do with fuel smell

 

ill definately get those on my list, also...my oil pressure gauge isnt working, do you think the oil pressure switch, or the gauge itself could be the problem
